ACID SlPHON-PUMP.

SPECIFICATION forming part of Letters Patent No. 231,841, dated August 31, 1880.

Application filed July 7, 1870.

To all whom it may concern:

Be it known that FRANCIS NICHOLS, deceased, late ofthe city and county of New London, State of Connecticut, and WOLGOTT B.

MANWARING and OLIN L. LW'ESEY, both of the said city and county of New London, did invent certain new and useful Improvements in Acid Siphon-Pumps, which invention is fully described in the following specification,

1e and represented in the accompanying drawings, making a part thereof.

These improvements have reference to an acid-pump, such as is described and shown in the United States Letters Patent Nos. 136,934

'15 and 175,489, granted to Francis Nichols,

above named, in March, 1873, and in March,

1876, and the several parts of which are described as made of glass, and relate to an improved construction of the parts, by which economy in construction and repair is secured,

and to an improved mode of connecting or joining such parts and of supporting the pumps, and also to the combination, with the apparatus, of an inclosing metallic case or shell, by which the several parts are protected against accident and breakage.

Figure 1 is a view of the complete pump in its inclosing-case and placed upon its supporting-stand. Fig. 2 is a vertical section of the 0 pump through the central part thereof, the several parts being separated from each other, so as to more clearly show their construction and mode of operation. Fig. 3 is a cross-section of Fig. 2 through 00 m. Fig. 4 is a cross-sec- 3 5 tion of Fig. 2 through y y. Fig. 5 is a cross-section of Fig. 2 through 22'. Fig. 6 is a side view of the inclosing and protecting case detached from the pump. I

The several parts of the pump or apparatus 0 are supposed to be made of glass, as is described in the patents before mentioned.

In the apparatus shown and described in said patents the upper portion of the pump or the eduction-neck, with its enlarged eXten- 5 sion, in which is situated the upper valve,

were made of a single piece of glass and continuous with each other. NVhen so made these parts could not be formed in a mold, but required to be blown, thus involving very con siderable expense in their first construction. According to the present improvements these parts-that is, the eduction-neck and the enlarged extension containing the upper valveas well as the body of the pump and the terminal additions of the body and eductionneck, are made in separate parts or pieces, which permits all these several parts to be formed by molds, thus rendering it possible to make them much cheaper and at the same time stronger or of heavier glass.

The body A of the pump is open at its top and bottom, and has in its lower part a valveseat, a, provided witha valve, to, opening upward, and having a stem, I), passing down through the valve-seat, and furnished with a 6 5 head, I), to prevent the valve rising too high.

At the top of the bod yA is a flange, 1, which projects outwardly, and furnishes means of connecting the parts together, and makes a seat for the support of the nozzle or part B, 0 which is placed within the body A. Near the lower end of the part A is a similar flange, 2, which forms a seat for a flange, 3, on the induction mouth-piece D. The valve-seat and the necessary openings therein are formed at the same time the body is pressed.

The nozzle or part B is placed within and extends down into the body A below the opening for the collapsible bulb J, and terminates at its lower end or bottom in a valve-seat, 0. which is provided with a valve, 0, opening upward, and prevented from rising too high by a headed stem, as is the valve a. This part B has at its upper end a flange, 4, extending round it and projecting outwardly, which rests upon the flange 1 of the body A, and by which it is supported. The eduction neck or part0 has also upon and around it an outwardly-projecting flange, 5, which rests upon the flange 4. on the part B, and has also at its other end 0 I a similar flange, 6, which furnishes a' seat for the flange 7 on the eduction mouthpiece E. The inner end, 0, of the neck 0 enters a little distance within the nozzle B, such part being smaller than and extending down into such 5 part B sutfieiently far to form an air chamber or space between the part B and the ends of C, thereby securing better action to the pump and also preventing the acid coming in direct contactwith the joints and packing. The outer end of the neck (1 is also smaller than and projects downward into the upper part of the mouth-piece E in the same manner, forming an air-space between the two parts for the same purpose, and the same construction is applied to the lower end of the body A, which enters the upper end of the induction mouthpiece D. These several parts-the body A, the nozzle B, the neck 0, the induction mouthpiece D, and the eduction mouth-piece E-are, as before mentioned, all made separately or in separate pieces, and are thus capable of being formed in molds, and can therefore be more cheaply manufactured than when they are blown, and in case of breakage of any part a new one can be easily substituted.

The mode or manner of connecting the several parts of the pump together at their joints is substantially the same. The description applies, however, more particularly to the joint or connection between the body A, nozzle B, and eduction neck 0. In the upper face of the flange 1, on the top of the body A, is formed a groove or recess, (1, extending entirely around such flange, and on the under surface of the flange 4 on the nozzle Bis a corresponding circular projecting tongue or head, (1, which enters, when the parts are brought together, the groove d. The groove dis, however, larger and deeper than the bead d, so as to furnish space for packing to be inserted between them, which will form an acid-tight joint when the parts are drawn together. A similar circular groove, 0, is fdrmed in the upper surface of the flange 4 on the nozzle 13, and a corresponding tongue or bead, c, on the under surface of the flange 5 on the neck 0, such groove 0 and bead 6 being constructed for packing, the same as the groove (1 and bead d.

Any packing may be used which will not be affected by acids. Parafline, wax, or asphalt, or two or more of those combined, are suitable and effectual for such purpose, and whether they retain a solid or hard condition or take a liquid form. The grooves form a cup to take and hold such packing, whether solid or liquid.

These parts-A, B, and Oare held and secured together by means of a metal ring, F, which has on its lower edge an inwardly-projectin g flange, 8, which passes under and takes hold of the flange 1 on the top of the body A, and in which enters from above a screw-ring, F, which has a flange or projection that extends over and takes hold of the flange 5 on the neck 0, and which, as it is turned down by a wrench, brings all the parts as tightly together as desired.

To provide for the easy connection and disconnection of the ring F from the part A the flanges S on the ring and 1 on the body or part A are partially cut away, as shown in Fig. 3, at corresponding intervals, so that the flange Scan be passed through the open spaces of the flange 1, and then be turned until the solid parts of the flange S on the ring shall pass under the solid parts of the flange 1 on the body A.

A rubber ring, h, may also be placed upon the flange 5 before the screw-rin g F is forced down, and to prevent such ring gathering or bnnching under the screw-rin g as it is turned a thin flat metal ring, 1', should be placed overit.

Holes 9 Sin the screw-ring F admit the insertion or attachment of a wrench to screw or unscrew the ring F.

The joints between the lower end of the body A and the induction mouth-piece D and between the outer end of the neck 0 and the eduotion mouth-piece E are formed by means of similar grooves fg and projecting tongues or beads f g, with intermediate packing, in the same manner as before described, and the parts are held and secured together by means of the bands G and H and screw-rin gs G and H working as before described, except that the screw-rings G and H enter the bands G and H from below, the wrench taking against .shoulders s s in the under side of such rings,

instead of, as in the ring F, in holes from above. The bands G and H are also formed with flanges a n, which are partially cut away, as shown in Figs. 4 and 5, which flanges pass over and take against the flanges 2 and 6, which are also partially cut away in the same manner as the flange 8 on the band F connects with the flange 1.

Instead, however, of connecting together the several parts of the pump, as before described, by means of grooves or cavities in one part and corresponding beads or tongues in the adjacent parts with parafline or other similar packing between such grooves and beads, ordinary rubber bands may be placed between the adjacent flanges or parts, which may then be brought together by the screw-rings, as before described, or the flanged surfaces, which lie upon each other, may be ground and then covered with a thin coating of sealing-wax or any varnish which will not be acted upon by the acid, and then brought together by the screw-rin gs, or their equivalent.

An elastic or collapsible rubber bulb, J is made use of for producing a vacuum in the body A and working the pump. The neck of such bulb, instead of passing over a flanged or headed tube or over a conical nipple, passes within a hollow nipple, J, which allows of ready and easy detachment when occasion may require.

A metallic case, K, of sufficient thickness for all required resistance, and perforated, so as to render it lighter and also permit the pump to be observed within it, surrounds the body A and protects it against accident and breakage. This case is made in two parts, opening on a vertical line through the nipple J, each half or part fitted with a collar cover ing one-half of such nipple, and rests upon the lower ring, Gr, so as not to press upon the glass underneath, and is connected together IIO by screws and nuts It, so as to be easily removable. A similar case, L, resting upon the ring orband F, so as not to press upon the glass, covers and protects the neck 0, and is connected to the case K, through a lug, Z, extending down over the band F,by nuts and screws 1.

From the band G, which connects the parts A and D of the pump, projects an. arm, m, to which is connected, by means of a lap-joint and bolt, the upper end of a trough, N, which receives and supports the glass or other tube 0, which connects with the eduction mouthpiece E. This trough may also be covered, so as to protect such tube.

A post or standard, P, also connects with and is firmly held to the arm at by means of a socket, P, formed, as shown in Fig. 5, in such arm m and the lap end of the trough N, and enters a supporting-frame, Q R, in which it can be adjusted at different heights by a screw, 9, and by which the whole apparatus is supported.

The post P is beveled or made tapering on one side, as shown in Fig. 1, so that the pump, should the tightening-screw 1) become loosened, cannot drop far enough to injure or break it.

The upright Q of the supporting-frame is connected to its bottom plate, R, by means of a nut or detachable connection, so that the parts can be separated from each other for convenience in packin The standard P and the trough N are made detachable from the band G, for the same purpose.

The apparatus may be converted into a siphon by lengthening the tube 0, and the siphonic action may at any time be interrupted by merely withdrawing the elastic bulb from the nipple in which its neck is inserted.

What is claimed is- 1. The cduction-neck and its extension or nozzle, composed of two separate portions, G and B, each portion of a shape capable of being formed in a mold, substantially as shown and described.

,of the set-screw should occur the 2. The eduction-pipe O and nozzle E, made in separableparts, the eduction-pipe being made with a contracted mouth adapted to fit into the nozzle and to form an air-space between the contracted mouth of pipe 0 and nozzle B, substantially as set forth.

3. The parts A, B, C, D, and E of the pump, made in separable pieces, each having connecting-flanges, as described, said flanges being provided with the tongues and grooves formed as shown and described, and adapted to operate as set forth.

4. The separable parts A, B, (J, D, and E of the pump, formed with flanges, provided, respectively, with the grooves d, e, f, and g, and tongues d, e,f, and g, and a suitable packing, for the purpose set forth.

5. The combination, with the connectingflanges of the pump and of the couplings, of metallic washers z and elastic bearings, substantially as shown and described.

6. The combination, with the coupling-ring G, having a projecting arm, on, of the trough N, for supporting the eduction or discharge pipe, the arm m and trough N being connected together by any suitable detachable joint.

7. In combination with an acid siphon-pump, a supporting-standard, a beveled adjustingrod, and a set-screw, wherebyif the loosening pump will be prevented from dropping far enough to injure or break it, substantially as shown and described.

8. The combination, with the acid-pump, its several parts being formed of glass, of a detachable protecting-shield, for the purpose set forth.
